Differential Privacy for Class-based Data: A Practical Gaussian Mechanism

no code implementations8 Jun 2023 Raksha Ramakrishna, Anna Scaglione, Tong Wu, Nikhil Ravi, Sean Peisert

In this paper, we present a notion of differential privacy (DP) for data that comes from different classes.

PULSE: Self-Supervised Photo Upsampling via Latent Space Exploration of Generative Models

16 code implementations CVPR 2020 Sachit Menon, Alexandru Damian, Shijia Hu, Nikhil Ravi, Cynthia Rudin

We present an algorithm addressing this problem, PULSE (Photo Upsampling via Latent Space Exploration), which generates high-resolution, realistic images at resolutions previously unseen in the literature.

New Techniques for Preserving Global Structure and Denoising with Low Information Loss in Single-Image Super-Resolution

1 code implementation9 May 2018 Yijie Bei, Alex Damian, Shijia Hu, Sachit Menon, Nikhil Ravi, Cynthia Rudin

This work identifies and addresses two important technical challenges in single-image super-resolution: (1) how to upsample an image without magnifying noise and (2) how to preserve large scale structure when upsampling.
